Wall Cavity Spray Foam in Erlanger, KY

In Erlanger, Wall Cavity Spray Foam is most impactful in pre-1950 homes with empty plaster wall cavities or settled fiberglass, and in 1950s-1970s drywall homes with original R-11 batts that have lost their air-seal. The install is drill-and-fill closed-cell foam through 1.5-inch access holes in each stud cavity, applied to the wall plane, the second-largest thermal surface after the attic.

Erlanger's airport-corridor stock went up in one contiguous building wave, so unlike the county's older mixed-era suburbs, its retrofit gaps repeat house to house rather than varying block to block. The same floor drains and utility penetrations that complicate a water-entry fix here also mark where spray foam needs to seal before it can form a continuous air barrier, since a batt alone never stops air movement through a gap. That housing profile shapes our typical scope for wall cavity spray foam in Erlanger. We run drill-and-fill through drywall access patches into stud cavities with original R-11 fiberglass, adding both R-value and the air-seal that fiberglass alone cannot provide.

Kenton County's best wall-cavity candidates are Covington's dense pre-war rowhouses and the older hilltop homes in Park Hills and Fort Mitchell, frequently built with empty plaster wall cavities, while Erlanger and Independence's mid-century drywall homes typically carry original R-11 batts that benefit from the added air-seal drill-and-fill provides.

Pre-1995 wall assemblies typically have no air barrier; drill-and-fill closed-cell adds both R-19 to R-21 in a 2x4 cavity and the integrated air seal that fiberglass cannot provide. Permitting in Erlanger routes through the Kenton County KY building department, and Climate Zone 4A R-value targets apply across the entire Cincinnati metro including both sides of the river.
